FIM ScriptBox Item

Summary

The objective of this script is to create a backup of all ObjectVisualizationConfiguration objects as XML that are exported by FIM Automation cmdlets.
Each Resource Control Display Configuration (RCDC) object is saved in a separate file and the name of the the file is the object's identifier.

The script takes one optional parameter: ConfigurationBackupPath.
ConfigurationBackupPath is the path to a customer backup folder.
The default is: C:\FIMBackup\ResourceControlDisplayConfiguration\

The script verifies whether the following three prerequisites are satisfied before processing the script code:

  1.  The script must be run by a user with administrative rights.
  2.  The script must be run on a computer running the FIM service.
  3.  The script must be run by a user that has write permissions to ConfigurationBackupPath.

If any of these conditions are not satisfied, the script stops and an error is displayed.
